I have been using the ICD-64 for a while now and I have a continuing problem where the debug mode won’t work. I have the following code which will load and “RUN” but will not run in debug mode. When trying to run in debug mode I get the following error. Please note that the unit would debug on Friday but won’t this morning.
This problem happens a lot with the ICD-U64 and the system will start and stop "debugging" at will.

Return error
“Could not start target: The target was not halted after reset. Check the target oscillator and MCLR. Make sure the target clock matches the clock fuse and the target is oscillating. Use View/Valid fused to find the correct clock fuse.”
